Cov Khoom Siv Tsim Khoom thiab Kev Tswj Xyuas Kev Ntsuas rau Cov Fiber Basalt Txuas Ntxiv Mus

1. Cov Khoom Siv Tseem Ceeb rau Kev Txuas Ntxiv Mus Basalt Fiber 
Txuas ntxiv mus basalt fiber kev tsim khoom siv "txheej txheem ib kauj ruam", uas yog tus cwj pwm los ntawm kev ua haujlwm yooj yim tab sis muaj kev cov nyom siab. Piv rau kev tsim cov roj carbon fiber, cov fiber basalt txuas ntxiv siv zog tsawg dua (tsawg dua 1/10 ntawm cov roj carbon fiber siv zog) thiab tsis muaj CO₂, SO₂, lossis lwm yam roj teeb meem, ua rau nws yog txoj kev tsim khoom zoo rau ib puag ncig thiab qis carbon. Cov khoom siv thermal tseem ceeb rau kev tsim cov roj basalt txuas ntxiv yog lub cub tawg, uas tau muab faib ua cov cub tawg crucible thiab cov cub tawg tank.

(1) Lub Rauv Kub
Ib lub cub tawg crucible feem ntau ua haujlwm nrog ib lub cub tawg rau ib lub bushing.
Cov Zoo: Me me, kev nqis peev tsawg, kev ywj pheej rau kev hloov kho cov txheej txheem hauv zos, thiab tsim nyog rau kev tsim khoom me me lossis kev tsim khoom tshwj xeeb.
Qhov tsis zoo: Kev ua haujlwm thermal tsawg, kev siv hluav taws xob ntau, qhov zoo ntawm cov khoom tsis sib xws, kev ua haujlwm tsis zoo ntawm cov khoom tsim tawm, thiab cov nqi tag nrho siab.
Tam sim no, cov cub tawg crucible tswj hwm kev lag luam fiber basalt txuas ntxiv mus, nrog rau lub peev xwm tsim khoom txhua xyoo ntawm 100–300 tons. Vim yog qhov puas tsuaj ntawm electrode thiab refractory cov khoom siv, cov cub tawg crucible muaj lub neej luv luv ntawm 6–12 lub hlis. Thaum lub sijhawm pib ntawm kev txhim kho kev lag luam, cov cub tawg crucible yog qhov zoo tagnrho rau kev tsim khoom me me thiab kev tshawb fawb txog cov khoom siv.
Hom Crucible Furnaces:

• Lub Cub Hluav Taws Xob Uas Muaj Hluav Taws Xob: Ua kom sov los ntawm cov roj ntuj thiab cua hlawv.
  Zoo: Kev tswj hluav taws yooj ywm, muaj peev xwm pib/nres sai.
  Qhov Tsis Zoo: Qhov kub ntawm nplaim taws qis, lub peev xwm yaj tsis zoo, pov tseg hluav taws xob vim yog nitrogen (78% ntawm huab cua) tsim cov pa phem NOₓ, thiab cua sov tsis sib xws ua rau cov yaj sib xws tsis sib xws.
• Lub cub tawg Crucible Hluav Taws Xob Tag Nrho: Sov sab hauv los ntawm phaj lossis pas nrig electrodes.
  Zoo: Kev ua haujlwm thermal siab, cua sov sab hauv zoo ib yam.
  Qhov Tsis Zoo: Lub neej luv luv vim yog kev hnav electrode, yuav tsum tau hloov pauv tag nrho tom qab kev puas tsuaj.

(2) Lub Rauv Rauv
Raws li qhov kev thov rau cov fiber ntau thiab zoo zuj zus, cov cub tawg tank (ib lub cub tawg nrog ntau lub bushings) tau dhau los ua qhov tseem ceeb rau kev tsim khoom loj. Lawv ua rau muaj kev tswj hwm qhov kub thiab txias nruj, txhim kho qhov sib xws ntawm cov yaj, cov khoom lag luam ruaj khov, thiab kev ua haujlwm siab, nrog rau cov peev xwm txhua xyoo ncav cuag ntau txhiab txog kaum txhiab tons.
Hom Lub Taub Hau Rauv:

• Lub Tshuab Hluav Taws Xob Txhua Yam: Siv cov electrodes pas nrig (kab rov tav lossis hauv qab).
  Zoo: Kev ua haujlwm thermal siab thiab cua sov sib xws.
  Qhov Tsis Zoo: Cov electrode kub, hnav tsis sib xws, thiab lub neej luv (~ 1 xyoos).
• Lub Qhov Cub Hluav Taws Xob Uas Muaj Hluav Taws Xob Tag Nrho: Siv roj av ntuj los ua kom sov nrog cua lossis cov pa oxygen ntshiab. Kev hlawv oxygen ntshiab yog qhov zoo dua rau kev ua haujlwm zoo thiab txo cov pa phem.
  Zoo: Lub neej ntev (3+ xyoo), txuag hluav taws xob nrog cov pa oxygen ntshiab.
  Qhov Tsis Zoo: Qhov kub thiab txias hloov pauv hauv cov yaj tob, txawm hais tias cov yaj ntiav txhim kho kev sib xws.
• Lub cub tawg hluav taws xob sib xyaw ua ke: Muab cov hluav taws xob sab saud thiab cov hluav taws xob hauv qab/sab ua ke.
  Zoo: Zoo dua yaj homogenization.
  Qhov Tsis Zoo: Kev tsim qauv nyuaj, qhov kub ntawm qhov chaw tsis sib npaug, kev poob hluav taws xob ntau los ntawm cov electrodes txias hauv dej, thiab lub neej luv luv vim yog kev hnav electrode.

(3) Lub Bushing
Lub bushing, feem ntau yog ua los ntawm platinum-rhodium alloy, yog ib qho tseem ceeb rau kev tsim cov fiber. Kev tsim khoom loj xav tau cov bushings muaj peev xwm siab. Cov bushings thawj zaug muaj 200 qhov; cov qauv tam sim no suav nrog 400, 800, thiab 1,200 qhov. Cov thev naus laus zis bushing nce qib sib koom ua ke nrog kev tsim kho lub tank cub tawg.

2. Kev Tswj Xyuas Kev Ntsuas Zoo 
Basalt yaj ua rau muaj teeb meem xws li qhov kub thiab txias ntawm kev kos duab / crystallization, kev ua kom sai, qhov rais qhov kub thiab txias nqaim, cov fiber tsis sib xws, cov dej noo ntawm bushing muaj zog, thiab qhov kub tsis pom tseeb. Cov yam no ua rau tsis ruaj khov thaum lub sijhawm kos duab fiber (piv txwv li, tawg, flyaway, qhov sib txawv ntawm txoj kab uas hla). Kev ruaj khov nyob ntawm peb yam:

• Kev Sib Npaug thiab Kev Ruaj Ntseg ntawm Cov Yaj: Ua tiav los ntawm kev sib tov cov khoom siv raw kom raug, kev tswj qhov kub ntawm lub cub tawg, kev tswj qib yaj, thiab kev tswj siab.
• Kev Tswj Xyuas Qhov Kub thiab Kev Ntsuas Kub: Xyuas kom lub bushing sov sib xws thiab zam kev siv lead ua.
• Kev Txhim Kho Cov Txheej Txheem Kos Duab: suav nrog kev tswj hwm qhov ceev ntawm kev kos duab, cov txheej txheem txias, thiab kev nruj ntawm cov fiber.

Cov thev naus laus zis tseem ceeb suav nrog cov txheej txheem tswj hwm siab heev rau kev sib xyaw cov khoom siv, qhov kub ntawm lub cub tawg, qib yaj, qhov siab ntawm chav tsev, qhov kub ntawm cov channel, qhov kub ntawm bushing, thiab qhov ceev ntawm kev rub. Cov no ua kom muaj kev tsim cov fiber basalt ruaj khov thiab zoo.
